我们提出了一个量子中继协议和架构，通过优化量子存储器缓冲时间来减轻纠缠态的退相干。该协议在所有嵌套层的平均访问状态下最大化可交换纠缠的速率。与不优化缓冲时间的规范协议相比，可实现的速率高出几个数量级。所提出的设计的优点是观察到的所有嵌套层次的中继器技术上可行的内存质量，纠缠生成和交换成功概率。
We propose a quantum repeater protocol and architecture that mitigates decoherence of the entangled states by optimizing the quantum memory buffer time. The protocol maximizes the rate of distillable entanglement in the average accessed state at all nesting levels. The achievable rate is higher by orders of magnitude in comparison to a canonical protocol that does not optimize the buffer time. The advantage of the proposed design is observed for all nesting levels of the repeater for technologically feasible memory quality, entanglement generation and swapping success probabilities.
